WELL-BUCKET.

Specification of Letters Patent.

App licaton led December 15, 1916.

To all whom it may concern:

Be it known that l, THOMAS J. McKiN Nox a citizen of the United States, and a resi ent of Livin ton, in the county of Polk and State o Texas, have invented a certain new and useful Improvement in Well-Buckets, of which the speciication.

This invention relates particularly to a bucket adapted to be used for cleaning and from drilled wells.

The bucket has a cylindrical cutting edge which loosens and scrapes off the silt and other trashy matter that may adhere to the well tube.'

The novel features of the invention are lierainafter described with-reference to the accmpanyingdrawing in which- Figure 1 is c, vertical section throiigh the lower portion Aof the bucket, showing the valve in closed position;

Fig. 2 is a similar view in o 'tion isf; horizontal sectonhrou'gh'the cylin 'cal portion ofi'fthe yalve, showing openings for the ing-'reed of 4material to the bucket; Fig. 4 isY a fra entary vertical section showuig a. modifie form of valve;

Fig. 5 is a fragmentary sectional view showingthe arrangement when the shelf and conical member are made of separate pieces, and

Fig. 6 isa fragmentary illustrating the use of a common lwith the bucket.

Referring to the drawings, the bod portion of the bucket which is cylindrical in form. The lower edge 2 of said bucket is crimped inwardly and upwardly to form an annular flange, designed to secure the lower edge of the conical or funnelshowing the'vadve sectional view lift valve 1 represents shaped member 3, the cross section of which decreases-uniformly toward its smaller end. This member 3, whic 'is open at both ends, has its upper portion flared outwardly to form a shelf 4, which 1n turn has its outer edge down turned and soldered or otherwise secured to the body portion 1 of the bucket, The shelf 4 serves to rigidly brace the conical member 3, and prevent any warping thereof. and also forms a seat for the valve 5. Thed said valve 5 which is slidable in the opening 9 defined at the smaller end of -the conical member 3, consists of a. cylindri following is a cal Bange portion 4*, definm Patented Mar. 19, 1918.

ortion 6, closed at its upper, and open at its lower end, and provided with openings for the admission of water when the valve is 1n open osition, as shown in Fig. 2.

The lower ec ge of the cylindrical portion 6' is flared outwardly at an angle to form a flange 8, adapted to engage against the walls of the cone 3 near the openin 9 of the valve seat, for the purpose of limiting the upward movement o the valve, as shown in Fig. 2.

The valve proper consists of a disk 10 of leather or other suitable material,- seated on the shelf 4. The disk 10 is interposed between and riveted orA otherwise secured to the closed end 1l of the valveholder or cylindrcal member 6, and a reinforcing plate 12. The said plate 12 extends slightly beyoud the edge of the opening 9 and serves to stillen the valve 10 and heat it evenly on the valve seat. y l

It will be readily seen that, when the bucket is lowered to the bottom of the well, the lower edge of the bucket which approximates the well in diameter and thus works in loose sliding contact therqvith will cut. away and loosen the silt and other trashy matter which adheres more or less to the well. The conical member will simultane- .ousl exert a pressure upon the material,

forcing it to raise the valve 10 and flow through the openings 7 into the bucket.

It will be understood thatthe above describedbucket may also be used simply for raising water, as the weight of the bucket is suilicient to sink the bucket, thus causing the valve to raise and admit the water.

In Fig. 4 I have shown a modified form of bucket, in which I have retained the same structural advantages, but have substituted for the valve described above a leather flap valve 10', having a reinforcing plate 12 secured thereto. The valve 10 is riveted or otherwise secured to the shelf 4 at a point to one side of the inlet opening defined at thel end of the conical member.

It will be appreciated that the structural details of the invention may bealtered withvout in any way impairing its eiiiciency or departing from the scope of the appende claims.

If desired the shelf 4 and conical member 3 may be made 'in separate pieces, as indi cated in Fig.e 5, and in such instance the shelf would equipped with a downturned g the opening for receiving the valve, which flange would be soldered or otherwise secured to the upper end of the conical member 3.

If desired I may, upon occasion, use an ordinary liftvalve in connection with the bucket, and such valve is indicated in Fig. 6, and constitutes principally a flexible member 15 for fitting over the opening in the shelf 4;, a rigid ieee 16 overlying the flexible member 15, and a substantially inverted U- shaped strip 17 suitably connected with the members 15 and 16 and having its ends projecting as indicated downwardly through the opening defined at the upper end of the conical member 3.

1. A Well bucket consisting of a cylin drical bodyportion, an internal conical member open at both ends and secured to the lower edge of the body, and a valve and Valve holder, the latter being adapted to slide in the top of the conical member and having an outturned flange at its lower edge which, when the valve holder rises, engages the conical member and thus serves as a stop, as described.l

Q. A Well bucket comprising a body of uniform diameter throughout its. length, a conical member open at both ends and arranged Within the lower portion of said body and having its lower edge flared out- Wardly so that as the valve rises it comes in contact with the cone, as described.

3. A well bucket comprising a cylindrical body, a conical open-end member arranged .Within the lower portion of said body and having its lower flaring edge secured to the latter, thus forming a cutting edge Whose outer side is cylindrical, as described.
